Ab Crunch Machine
Technique guide
Set-up
- Adjust the seat so the pads rest against your upper chest, or the handles sit by your shoulders.

How to do it
- Curl your torso forward and down, bringing your ribs towards your hips.
- Squeeze your stomach at the bottom.
- Return slowly to the upright start.
Coaching cues
- The movement comes from your spine, not your hips.
- Breathe out as you crunch.
Common mistakes
- Pulling with the arms.
- Using a weight so heavy that you rock to move it.
